4 Claims.

This invention relates to new and useful improvements in shutters for windows and more particularly to shutters such as are used during wartime blackout conditions.

The principal object of the present invention is to provide a blackout shutter which is collapsible, but firmly mounted in a window frame so that it is always in a position for ready use.

Another important object of the invention is to provide a blackout shutter which is principally constructed of wood or some other nonessential materials, thus conserving highly essential metals.

Other important objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings-- Figure 1 represents a perspective View showing a window with the collapsed shutter disposed therein.

Figure 2 is a vertical sectional view through the window frame and collapsed shutter and showing the shutter panels in lowered position by dotted lines.

Figure 3 is an outside elevational view of the shutter extended.

Figure 4 is an edge elevational view of the shutter extended.

Figure 5 is an enlarged detailed sectional' view taken substantially on the line 5-5 of Fi ure 3.

Figure 6 is an enlarged horizontal section on the line 6-6 of Figure 2.

Figure 7 is an enlarged detailed sectional view taken substantially on the line 1-1 of Figure 3.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to a conventional window frame, while numeral 6 generally refers to the present invention. I

The frame 5 includes the usual side portions l, '1, sill portion 8 and top portion 9.

The shutter 6 preferably consists of three panels Ill, II and I2. However, two panels, or more than three may be employed when seen fit.

Channeled guide members 13 and M are secured to the vertical edges of the panels II, l2 to accommodate the end portions of the panels In and H. As can be seen in Figure 6 the guides l8, l4 have offset flanged portions l5 which define trackways for the accommodation of springs I5 and further, this ofiset I5 serves to accommodate channeled guides 13 with respect to the guides M, as is clear in Figure 6.

As can be seen in Figure 5, springs are provided at the upper end of the panel H and at the lower end of the panel 10, and further springs I6 are provided at the upper end of the panel I! and at the lower end of the panel ll.

These springs are in the path of each other so that when the panels are extended to their fully opened position as shown in Figure 3, the springs abut, as shown in Figure '7, to prevent the panels from being pulled entirely apart.

A handle I1 is provided on the lower portion of the panel l2.

A cleat I8 is provided at the upper edge of the panel I0 and this is to be secured to the horizontal portion 9 of the window frame 5. A supporting cleat I9 is preferably provided at the lower edge of the panel l2 so as to rest on the window sill 8 when the panels are in fully extended position.

Obviously, the springs 16 offer Sufficient friction to hold the panels in any position at which they are left. By pulling downwardly on the handle 11, the panel l2 will first move downwardly until its springs l6 engage the springs l6 at the lower end of the panel I I, when the lower panel II will be pulled downwardly until it is stopped by its spring I6 engaging the springs N5 of the panel 10.

Obviously, during war times, this shutter when extended, will preclude the possibility of light beams to any extent passing through the window.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A blackout shutter comprising a plurality of panels, means slidably connecting the panels in overlapping relation, and springs carried by the opposed faces of adjacent panels to aflord frictional retaining means therefor, said springs forming stops cooperating with each other for limiting sliding movement of the panels.

2. A blackout shutter comprising a plurality of panels and slidable connections between the 45 panels, said panels being provided with springs interposed therebetween to afford frictional retaining means.

3. A blackout shutter comprising a, plurality of panels and slidable connections between the panels, and guide means comprising channeled members secured to the vertical edge portions of certain of the panels to receive the edge portions of complementary panels.

4. A blackout shutter comprising a plurality of panels and slidable connections between the panels, and guide means comprising channeled members secured to the vertical edge portions of certain of the panels to receive the edge portions of complementary panels, and spring members mounted in the channeled members to offer friction and. retention of the panels.
